To all whom it may concern; 7 Be it known that we,'FRnnER1cK J. HUM-rrmnr and HUBERT R. HUMPHREY, citizens of the United States, residing atKalamazoo,

county of Kalamazoo, State of Michigan, have invented vcertain new anduseful Improvements in Gas-Lamps, of which the following is aspecification,

This invention relates to improvements in gas lamps.

The main objects of this invention are: First, to provide an improvedgas lamp of the inverted burner type. Second, to provide in a gas lampof the inverted burner type, an improved burner structure. Third, toprovide in a gas lamp of'.the inverted burner type, an improved burnerin which the burner screens are readily accessible without disassemblingtheburner, and the parts of the burner arearranged so that they do notbecome unduly heated in use. p

' Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

lVeaccomplish the objects of our inventionby' the devices and meansdescribed in the following specification. v v The invention is clearlydefined and points edout in theclaims. 1 4 A structure, which is apreferred embodiment of our invention, is clearly illustrated in theaccompanying drawing, forming a part of this specification, in which:

I Figure I is a detail view, partially in ver-' tical section, of astructure embodying the features of our invention. Fig. ILis ahorizontal section taken on a line corresponding to the broken line 22of Fig I, looking'in the direction of the little arrows at the end-- ofthe section lines. Fig. III is a detail plan view of one of the screenholders 23.

In the drawing, similar reference characand provided withdownwardlyprojecting nipples at into which the tube-like burner tipmembers 5 are threaded, the burner tips 6; being threaded lnto the lowerends of these' members 5.

The burner member 2 is provided with an upwardly andlaterally-projecting inlet tube Specification of Letters Patent.

Patent d J 1 1.23, 1912'. Application filed reb' ar 15, 1911. serial No.608,694. 1 v I r 7,-the outer-end of which projects: through th'echimney casing 8, as is clearly illustrated in the drawing. The passagearms 3 are disposed between the chimney flues 9 andabove the chimneydeflector plate 10 -The deflector late isp'rovided with openingsregisteringwith the nipples 4011 the burner passage arms 3. The burnertip members .5; are

threaded into the nipples and shouldered at 11 to clamp the plate 10. Onthe under side 1 I of theplate is a flange-like portion 12 -s ur--rounding the burner tips to directthe heated gases and products ofcombustion. to the chimney fiues and the incomingeirtothe burner-tips.

The mantles are not shown. hereinas their arrangement will be readilyunderstood;

The plate 10 is provided with airinlet openings 13 through which the airenters" from the chimney casing, the chimney plate having airinletopeningsll into the globe 16. The globe 16 is carried by theglobe"sup-- porting band 17. Thisband is, in practice, hinged, but asthis featureforms no par't'of the present invention, we donot-illustrate or describe the same herein. i

The inlet tube 7is preferably provided" with an integrally formed supplypipe couf 'pling 18. This coupling does not communr cate directly withthe tube, but the gas is de' livered to the inlet tube through thevalvecasing 19 which arranged on the outside of the chimney casingandconnected to the supply pipe coupling member 18 by means of thecoupling member20, which projects through the'casing. On the valvecasing is a gas delivery nozzle 21, delivering to the gas inlet tube.7.

The details .of the nozzle, and supply valves are not illustrated, asthey form .no part of the present invention.

The burner passage 'arms are adapted to receive the screens 22, which,in the structure 1llustr-ated,'are cylindrical and carried 'by'thecylindrical screen holders 23 adapted to slip into the open outer endsof the arms,

as clearly illustrated. These screen holders areopen at their inner endsand have open ings on their under sides at 24; The holders are closed attheir outer ends and serve toclose the open ends of the passage arms.

The casing is provided with openings 25 5 through which the screens maybe" intro-.

duced' or removed. The holders are 're--.

l a chimney passage arms; a .on said burner bayonetslots 26 adapted toengage the pinserable modifications in structural details are but asthese modifications will no possible,

readily understood by those skilled doubt be .in the art towhich thisinvention relates,

we do not at-tefnpt'to illustrate or describe the same herein.
